For the sake of discussion lets say there are two companies making widgets. I wish to start a widget company also. I send my proposal to the industrial council of widget manufacturing, presumably made up of people who work for widget company one and two, since these are the people that would be most directly affected and have the most knowledge of widgets. Why on earth would they let me open a competing business and risk losing their market share and therefore their bargaining ability in determining their remuneration? Entrepreneurialism is not an overriding concern of mine in parecon but your answer seems to run counter to human nature. In my opinion most people would not risk both job security (reduction in sales of widget company one means a reduction in workforce) and power (with fewer players in a given field more power is assigned to each player) for the sake of some sort of perception of fairness. Perhaps I'm overly pessimestic.
